reductive/rɪˈdʌktɪv/ adj.以简释繁的

innovation/ˌɪnəˈveɪʃn/ n. 创新

例句:

1. The batteries had a life span of six hours.

2. In aprotic solvents magnesium effects pinacol reductive coupling of aldehydes and ketones. 

在非质子性溶剂,镁对频纳醇与醛和酮的还原耦合反应也有一定效果。

3. The vegetarian burger was an innovation which was rapidly exported to Britain.

素食汉堡是一种迅速传到了英国的新开发食品。

结构分析:

第一句:To represent this span of human history as a set of simple stripes是to do结构的不定式作主语(this spanof human history 是宾语,其中this是前置定语,of human history是后置定语,as a set of simplestripes是介词词组作状语), may seem是系动词词组, reductive是形容词作表语

第二句:These是主语, are是系动词, years是表语, which引导定语从句,作主语, saw是谓语(see的过去式),world wars, technological innovation, trade on an uNPRecedentedscale and a staggering creation of wealth是宾语,用2个逗号连接3个并列宾语(on an uNPRecedentedscale and a staggering creation of wealth是后置定语)。
